My 2007 VTX 1300 Retro started sputtering, lost acceleration, top speed dropped to 70? Bike has 8200 miles. When I bought it about 2 months ago it had around 7300. Had been setting up. Ran good but occasionally sputtered and backfired. I am thinking ethanol related problem and used a gas additive. Problem ceased but came back.

You must turn your gas tank upside down to drain it.

SOURCE: no fuel to carb, I think..

I would check the vacuum line that opens the fuel feed valve. It's located right under the fuel shutoff valv and is fed by the #2 carburetor.

You may have an air leak (extra air getting in) between the carbs & the engine. Inlet manifold rubbers do crack on Hondas but Yamahas are the worst.
Check for cracks, check the o rings (each end of inlet manifold) & check for leaks from air-box to carbs
Carbs need to be balanced (synchronised) to let the engine run smoothly but will not produce those symptoms if left unbalanced.
You should also check the HT leads & spark plug caps for shorting, run the bike in the dark & look for sparks going to earth (sometimes you can only hear a ticking as the spark jumps across). Make sure the leads are not touching anything during this procedure

hi,sounds like you have a blocked main jet in one of the carbs,when the fuel sits in the bowls it will evaporate and leave behind a residue that is quite difficult to remove even with a carb cleaning compound,what i do in this case is remove the carbs,remove all the jets,place all the jets in a saucer or dish and fill with petrol,leave them for a few days,this will soften the residue,then use compressed air or a crc typecan with carb cleaner and force clean them by squirting the fluid through them,do not use(as some people do) a piece of wire to clean through them,this will scratch the inside of the jet and alter the fuel flow charicteristics of the jet and render it all but useless,once you have them all absolutely spotless,reassemble and put the carbs back in,just about put money on it that your problem will dissappear,hope this helps...cheers

sounds like a problem with the sidestand switch. look for the sensor located at the top of the sidestand,when up it pushes in a sensor.
